Gaga and “Vampire Diaries” actor Kinney reportedly began dating in July, when he starred in her music video for “You and I,” a song widely believed to be about Gaga’s ex, Luc Carl. While the two kept their relationship quiet for months, they were photographed together for the first time earlier this month, walking down the street with their arms locked around the other’s shoulders. The two were spending time together at Kinney’s San Diego beach house.

Sackett shares that she actually ran into her ex and his new girlfriend while they were there.

“They looked like they’d been partying for a while,” Sackett said. “Gaga had full makeup, her hair was a total mess and she was smoking a cigarette. I talked briefly with Taylor, but Gaga didn’t talk to me at all — it was super-awkward and uncomfortable.”

Sackett reveals that she found out about Kinney’s involvement with Gaga when he accidentally called her while with the “Marry the Night” singer. Sackett says she quickly broke up with him.

“He apologized by text and on the phone,” said Sackett. “But I wasn’t giving him the time of day.”

While Gaga has not confirmed her relationship with Kinney, she did say in October, “You know I don’t talk about my love life, but I’m very happy.”
